Brief Introduction:

1. Structure

The line boring Machines consist of boring rod, main axis box, feeding box power unit, support, end surface machiningparts, milling parts, etc.

2. Operation

First, the dimension of manufactured hole shall be confirmed. Then, the central point must be found for fixing the support, and boring rod, feeding box, main axis box, power unit shall be mounted. The appropriate cutter frame then shall be chosen for processing.

3. Applying scope

Processing and repairing of pipe inner hole, engineering machine, large scaled ship fixed hole, ship axis hole, etc. Providing services for many fields, such as mining, marine engineering, shipping, petrol, electric power, etc.

Performance:

1. Impact structure, easy to operate, install and dismantle.

2. High-strength alloy steel boring rod and accurate transmission structure can guarantee the accuration and efficiency of processing.

3. High-accurate spherical roller bearing is used in supporting seat, enabling quick installation and adjustment of machine before machining.

4. Vertical, horizontal or tilt installation can be chosen.

5. Power unit includes electrical and hydraulic power, equipped with remote control box, which make much more convenience.

6. Many kinds of machining can be achieved with appropriate parts, such as boring, end surface machining, drilling, expanding hole, blind hole boring, etc.

7. The boring cutter can be adjusted based on the holes' diameters for its impact structure.

Structure

This series large line boring machines are for large holes' processing, the length of boring bar is usually about 4m to 10m, which can be mounted with processing attachments, taper boring devices.

The powful drive makes the cutting easier.

A － Feeding box(two gears, 0.16mm, 0.28mm)

B － Spinble box/headstock box

C － Cross support

D － Toolpost

E － Center support

F － End face processing device

G － Boring bar

H － Manual feeding handwheel

Composition

1. Feeding box

1.1 BP110 line boring machine has two types of feeding box, feeding distance can be adjusted at two gears , 0.16mm, 0.28mm,

1.2 BP150, BP200, BP250 has three feedings, 0.16mm, 0.28mm, 0.5mm, and can choose the different ones, according to the processing requirements.

1.3 Both two structures can manually/automatically feeding, and have the feeding handwheel.

1.4 The reversing handwheel has three options, normal-reverse and stop.

 

2. Headstock

Spindle box with aluminum structure, the turbine uses a high strength and high wear-resistant alloy of copper to extend its serve-life, and also focus on improving the heat dissipation to enhance its performance.

3. Boring bar

Length of boring bar is different from the boring hole's length, the length of the supports on both sides, motivation and feed box length should not be counted , so please tell us the actual length of the workpiece holes so that we provide the most suitable length of the boring bar.

       

4. Toolpost

     The boring holes' size can be controlled by increasing the tool pads

5. Support

   5.1 there are cross support and center support available.

   

6. End surface Machining Device
